¡Atención! Esta unidad ha sido diseñada para instalarse en áreas de acceso
restringido. Área de acceso restringido significa un área a la que solamente
tiene acceso el personal de servicio mediante la utilización de una herramienta
especial, cerradura con llave, o algún otro medio de seguridad, y que está
bajo el control de la autoridad responsable del local.

Varning! Denna enhet är avsedd för installation i områden med begränsat
tillträde. Ett område med begränsat tillträde får endast tillträdas av
servicepersonal med ett speciellt verktyg, lås och nyckel, eller annan
säkerhetsanordning, och kontrolleras av den auktoritet som ansvarar för
området.

Preventing Electrostatic Discharge Damage to the Services Gateway

Many services gateway hardware components are sensitive to damage from static
electricity. Some components can be impaired by voltages as low as 30 V. You can easily
generate potentially damaging static voltages whenever you handle plastic or foam
packing material or if you move components across plastic or carpets. Observe the
following guidelines to minimize the potential for electrostatic discharge (ESD) damage,
which can cause intermittent or complete component failures:

Always use an ESD wrist strap or ankle strap, and verify that it is in direct contact with
your skin.

CAUTION:

For safety, periodically check the resistance value of the ESD

strap. The measurement should be in the range of 1 to 10 Mohms.

When handling any component that is removed from the chassis, verify that the
equipment end of your ESD strap is attached to one of the ESD points on the chassis.

Avoid contact between the component and your clothing. ESD voltages emitted from
clothing can still damage components.

When removing or installing a component, always place it component-side up on an
antistatic surface, in an antistatic card rack, or in an electrostatic bag. If you are returning
a component, place it into an electrostatic bag before packing it. See
